So is this no longer an option to purchase a new harness?

Go to Fordpartsgiant.com or TASCA Ford parts. I got a new ford complete engine harness for about $600. Sure beats the list price. Part # 6C2Z-12B637-UA

The guys at Tasca were really helpful. (you will have 15 minutes of wait time but they will answer, I couldn't get them to return a call though) You need to get the harness code off the tag under the Air intake.
If these are becoming unobtainium like everything else thes days I may need to pull the trigger and throw it on the shelf. I guess one could rebuild a harness with new wire, plugs, and pins as a snowy day project.
Based on the physical appearance of my harness I'm amazed I haven't had any issues. Knock on titanium.
